CVSS: 10.0EPSS: 1%CPEs: 7EXPL: 1CVE-2023-3961 – Samba: smbd allows client access to unix domain sockets on the file system as root
https://notcve.org/view.php?id=CVE-2023-3961
11 Oct 2023 — A path traversal vulnerability was identified in Samba when processing client pipe names connecting to Unix domain sockets within a private directory. Samba typically uses this mechanism to connect SMB clients to remote procedure call (RPC) services like SAMR LSA or SPOOLSS, which Samba initiates on demand. However, due to inadequate sanitization of incoming client pipe names, allowing a client to send a pipe name containing Unix directory traversal characters (../). This could result in SMB clients connect... • https://access.redhat.com/errata/RHSA-2023:6209 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 6.8EPSS: 0%CPEs: 7EXPL: 0CVE-2023-4091 – Samba: smb clients can truncate files with read-only permissions
https://notcve.org/view.php?id=CVE-2023-4091
11 Oct 2023 — A vulnerability was discovered in Samba, where the flaw allows SMB clients to truncate files, even with read-only permissions when the Samba VFS module "acl_xattr" is configured with "acl_xattr:ignore system acls = yes". The SMB protocol allows opening files when the client requests read-only access but then implicitly truncates the opened file to 0 bytes if the client specifies a separate OVERWRITE create disposition request. The issue arises in configurations that bypass kernel file system permissions che... • https://access.redhat.com/errata/RHSA-2023:6209 • CWE-276: Incorrect Default Permissions •
CVSS: 6.8EPSS: 0%CPEs: 11EXPL: 0CVE-2023-42669 – Samba: "rpcecho" development server allows denial of service via sleep() call on ad dc
https://notcve.org/view.php?id=CVE-2023-42669
11 Oct 2023 — A vulnerability was found in Samba's "rpcecho" development server, a non-Windows RPC server used to test Samba's DCE/RPC stack elements. This vulnerability stems from an RPC function that can be blocked indefinitely. The issue arises because the "rpcecho" service operates with only one worker in the main RPC task, allowing calls to the "rpcecho" server to be blocked for a specified time, causing service disruptions. This disruption is triggered by a "sleep()" call in the "dcesrv_echo_TestSleep()" function u... • https://access.redhat.com/errata/RHSA-2023:6209 • CWE-400: Uncontrolled Resource Consumption •

10 Oct 2023 — A flaw was found in shadow-utils. When asking for a new password, shadow-utils asks the password twice. If the password fails on the second attempt, shadow-utils fails in cleaning the buffer used to store the first entry. This may allow an attacker with enough access to retrieve the password from the memory.
